Title: Fix #3521 Use an object as the process.env proto

For some reason, though, it looks like EnvGetter is not called for the
key `__proto__`, so I can't make the info->Data() accessible. However,
putting the Object.prototype keys there, in such a way that they are not
OwnProperties, and are supersceded by environs, makes process.env much
less weird.
